—Average distance from the sun:141,633,260 miles (227,936,640 km). By comparison: 1.524 times that of Earth. —Perihelion (closest solar approach): 128,400,000 miles (206,600,000 km). By comparison: 1.404 times that of Earth. —Aphelion (farthest distance from the sun): 154,900,00...
They tend to occur when Mars is closest to the Sun, and have been shown to increase the global temperature. Mars’ average distance from the Sun is roughly 230 million km (1.5 AU) and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer ...
Let us review the known conditions on Mercury, and shortly on Mars, because we will compare them. Mercury has the most eccentric orbit of all the planets; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km. It takes 87.969 earth days to ...

Marsdistance from theSunand orbital eccentricity Mars Features Moons Mars has two small moons,PhobosandDeimos. They were discovered in 1877 by astronomer Asaph Hall, who named them for the Latin terms “fear” and “panic”. These moons are thought to be captured asteroids and are among the ...
and speed of rotation in its orbit. The asteroid belt is located at an average distance of 254.5 million kilometers from the Earth. Astronomers believe that the asteroid belt is composed of terrestrial material that was never able to form into either a planet or of the remains of a planet ...
As inputs, the mean Mars-Sun distance of 1.52 AU was used with a solar zenith angle of 0∘, for a solar longitude of 0∘, at 0∘N,0∘E (using the ‘Looking up to the Sun’ viewing geometry). The Planetary Spectrum Generator’s standard martian atmospheric profile with no...
it’s almost always too far away to reveal much detail, even in a big backyard telescope. When Mars is at its farthest point from Earth, at a distance of 225 million kilometers, the planet shines at a modest magnitude +1.8 and has a disk that’s just 3.5″ across. That’s about th...
Earth orbits the Sun at anaverage distance (aka. semi-major axis) of 149,598,261 km – or one Astronomical Unit (AU). This orbit has a very minor eccentricity (approx. 0.0167), which means its orbit ranges from147,095,000 km (0.983 AU) at perihelion to 151,930,000 km (1.015 AU)...
